FreeBSD build regressions

["Alex Bennée" <alex.bennee@linaro.org>]

Hi,

It looks like the build has been broken on Cirrus since at least 7b2c4c:

  https://cirrus-ci.com/github/qemu/qemu

I did attempt to have a look but "vm-build-freebsd" seems to be failing
with a different error:

Tracking back to before the previously mentioned commit it was still
failing which makes me think something has happened to the BSD image (or
something is missing since the build changes). I'd appreciate it if
someone with more FreeBSD knowledge can look into both regressions
because frankly I find it exhausting enough tracking down Linux
regressions when they occur.

Thanks,
